Investment in Irrigation Systems Is Vital in Preparing for the Next Climate Shock

Approximately 95% of Africa’s arable land depends heavily on rainfall, which is vulnerable to climate shocks such as drought. El Niño-induced drought expected to hit some parts of Africa, particularly southern Africa, is going to worsen the situation. At the Africa Food Systems Forum in Kigali, Rwanda, governments and development partners are calling for more investment in irrigation systems to reduce dependence on rain-fed agriculture by farmers, including small holders who make up 80% of all farmers in sub-saharan Africa. Building More Irrigation Systems Only 5% of Africa’s arable land is under irrigation. Asia irrigates about 7 times more than Africa, as it holds about three-quarters of the entire world’s irrigated land. “Some irrigation systems have been developed. The task now is to take it to scale,” said Nigeria’s Minister of Agriculture, Senator Abubakar Kyari, at a side event organised by the International Water Management Institute (IWMI). “The technology is there and the workforce is there. What we need is collective action.” IWMI is a global research organisation addressing water challenges in developing countries, working with governments, civil society, and businesses. When El Niño hit the southern Africa region in the 2023/2024 agriculture season, it triggered one of the driest mid-seasons in over 40 years. It devastated rain-fed maize production, leaving over 26 million people facing hunger in Botswana, Lesotho, Malawi, Namibia and Zambia. These countries declared national drought disasters to mobilise resources from the public purse, private sector and humanitarian agencies. In preparing for the next El Nino, Abubakar said agriculture cannot remain at the mercy of the seasons. He said Africa should sustainably manage and deploy its vast water schemes. “This is not a continent of scarcity but of strategic abundance,” he said. “Our task now is not to apportion blame but to break that cycle.” Africa holds about 9% of the world’s renewable freshwater systems. Abubakar proposed the adoption and operationalisation of the African Union Framework on Irrigation Development and Agricultural Water Management to enhance water control and increase farmer-led irrigation. This framework is a continental blueprint published in 2020 to boost food security, adapt to climate change, and modernise agriculture across member states. Abubakar said there is a need to innovate financing to close the investment gap and to strengthen transboundary water appropriation. “We must move from sharing drops to sharing benefits. Establishment of enforceable cooperative frameworks. To scale up climate-smart irrigation and put farmers at the centre of irrigation development. Also to open opportunities for young people in irrigated value chains,” he said “We must turn continental commitments into actionable delivery. We have articulated the future we want. We must translate that.” Policy is key to enabling a working, favourable environment for increasing investment in the agriculture sector. Speaking at the same event, Vincent Kabuti, Irrigation Secretary in the Ministry of Water, said governments should be able to put in place mechanisms for farmers to hold the government accountable. He said large commercial irrigation systems are essential in complementing farmer-led irrigation systems. “We have a lot of water, but it is the investment that we do not have,” Preparing for the next El Niño Southern Africa expects the next El Niño in the 2026/2027 agricultural season, according to scientists. The weather phenomenon was officially declared on 11 June by the US National Oceanic and Atmospheric Administration (NOAA). NOAA confirmed that ocean temperatures in equatorial areas of the Pacific Ocean had remained more than 0.5 °C above average for several months. El Niño occurs when trade winds in the Pacific reverse direction, causing warmer water to flow into central and eastern areas of the world’s largest ocean. In Africa, it normally brings El contrasting weather extremes, causing severe droughts in southern Africa and heavy, flood-triggering rains across East Africa. Drier conditions, which scientists are anticipating, are expected to threaten staple crop yields like maize in southern Africa. Reduced food security risks compounding pressure on food price inflation and acute malnutrition among children. Abubakar said irrigation systems cushion farmers from droughts and boost food security, create jobs and boost the livelihoods of approximately 439 million Africans living in extreme poverty. Tilahun Amede, a director of Climate Sustainable Productivity and Resilience at Alliance for a Green Revolution in Africa (AGRA), an institution focused on scaling agricultural innovations that help smallholder farmers towards increased incomes, better livelihoods, and improved food security, said countries must integrate water in every aspect of agriculture. “African governments must invest in water and irrigation systems,” he said. “We also need to create a market for farmers to increase their incomes so that they can adopt irrigation systems.” IPS UN Bureau Report Related Articles Strengthen Africa’s Seed Systems as El Niño Threat Becomes Reality Again Field-Based Research Is a Lifeline for Zimbabwe’s Food Security
